9 Claims. (Cl. 3658.5)

My invention relates to the heel back construction of low shoes. Its principal object is to prevent slipping or rubbing of the foot up and down against the heel back with consequent chafing of the foot and wear and tear of the hose. It consists principally in a patch of general triangular form secured with its base uppermost and secured to the heel back in such manner that its lower part and side margins are left free. It also consists in securing such a patch by a line of stitching in the form of the letter w or other form with upwardly and inwardly converging lines. It also consists in cutting a w-shaped notch in the top of the heel back conformable to the stitching. It also consists in the parts and combinations and arrangements of parts hereinafter described and claimed. In the accompanying drawing wherein like numerals refer to like parts wherever they occur;

Fig. 1 is a view of a low shoe embodying my invention.

Fig. 2 is a cross sectional view on the line 22 of Fig. 1 showing my patch in position in the shoe,

Fig. 3 is a detail view of my preferred form of patch,

Fig. 8 is a view of a plain patch applied to a plain lining.

According to the present invention, a patch 1 40 of general triangular shape is stitched to the upper part of the lining 2 of a low shoe A with its point extending downwardly at or close to the heel back seam 3. Preferably the stitching 4 is arranged symmetrically with respect to 45 the heel back seam in the form of the letter W,

the outer sloping lines 5 of stitching being substantially parallel to the side edges of the patch but somewhat inwardly therefrom (say about one-fourth of an inch) and extending from the top of the lining somewhat less than half the distance to the lower point of the patch. The top of the lining may be continuous, as illustrated in Fig. 7; but preferably it is formed with a W-shaped notch in the top margin thereof disposed symmetrically with respect to the heel back seam, as shown in Fig. 4. That is, it is preferable to remove the portion of the lining above the W-shaped stitching which secures the patch thereto. Preferably, the side margins of the patch are notched or serrated, as shown in Fig.1

3; but such sides may be plain or entire, as

shown in Fig. 6. p I 1 It is common practice to make the lining for the back of a low shoe in two matched-pieces united by a vertical line of stitching constituting 0 the heel back seam 3, with its seam allowance pressed flat and with the finished-face of the leather exposed. Preferably my patch is made of the same material as the lining and stitched to the lining with the rough or unfinished facethereof exposed. In other respects, no change is needed in the construction of a low shoe'in order to apply my invention thereto.

- In service, my patch, to a large extent, prevents slippage of the foot relative to the shoe, and

to an ever greater extent renders slippage innocuous: for the roughness of the face of the patch tends to keep the hose from slipping relative to the patch, and the stitching of the upper part of the patch to the lining, while permitting the lower part of the patch to slip, limits such slippage to a narrow range. The fact that the smooth surface of the patch is in contact with the smooth surface of the lining insures the slippage of the patch on the lining rather than the slippage of the hose on the patch; at the same time the stitching of the upper part of the patch to the lining limits and offsets the freedom of the lower part of the patch to slip. In this limiting and ofisetting action, the upward convergence of the innermost lines 6 of stitching are quite beneficial. It is also noted that notching the lining back of the top of the patch provides recesses against the edges of which the hose can grip' and thereby escape the tendency to creep downwardly.

. Obviously the invention is not limited to the particular details hereinbefore described. For instance, while I have described the patch as of general triangular form, the important consideration is that it should be wider at the top and taper towards the bottom. Likewise the stitching may be in curved or sinusoidal lines rather than straight or W-shaped lines; and instead of terminating inwardly from the side margins of the patch, the stitching may be extended to the edges thereof. Likewise, the patch may be made of leatherwith both sides rough, or of fabric or laminate material.

What I claim is:

1. A low shoe provided with a downwardly tapering triangular patch secured to the upper portion of the lining at the heel back seam and along lines extending outwardly and downwardly therefrom in the direction of the middle portions of the sides of said patch, the lower portion of said patch being in front of and free from the lining. ,7

2. A low shoe having a'lining which has a notch in the top margin at the heel back and a flexible downwardly tapering triangular patch over the upper portion of the lining at the heel back below said notch an'd'with 'itslowerpoi'tion in front of and free from the lining, said free portion having upwardly converging upper edges secured to said lining. i.

3. A low shoe provided with meme down wardly tapering triangular patch secured by.

stitching to the upper portion of the lining at {the heel back with the portion below said stitching in front of and free from the lining, said stitching comprising lines arranged like the letter W.

4. A low shoe having a w-shaped notch in the top margin of its lining at the heel back and a flexible downwardly tapering patch somewhat wider than said notch attached to the lining along-and substantially parallel with the upper W-shaped margin thereof, the portion of said patch below such line of attachment being free.

- from the lining.

5. A low shoe provided with a downwardly tapering patch at the heel back seam with its lower portion and its side margins free from the lining and with its upper portion secured to said lining *bystitching somewhat below the top thereof and seam towards the lower ends of said first men tioned stretches.

6. A low shoe provided with a flexible downwardly tapering triangular patch located in front of the lining at the heel back seam with its entire 5 outer surface'and a downwardly tapering triangular patch over the upper portion of the lining l5 at-the heel back with its entire lower portion free from the liningand terminating above the insole, saidpatch having a smooth surface next to the lining and a rough outer surface, said free portion having upwardly converging upper edges secured to said lining.

8. A low shoe having in its heel portion a lining of leather with itsexposed surface smooth, and a triangular leather patch over the upper portion of the liningat the heel back in front of and with 525 its lower portion free from the lining, said .patch having a smooth surface next to the liningand a rough outer surface, said free portion having upwardly converging upper edges secured to said lining.

9. A low shoe having in its heel portion a lining of leather with its exposed surface smooth, and a triangular leather patch secured to the upper portion in front of and free from the lining by lines of stitching arranged in the form of 35 W, said patch beingotherwise free from the lining'and having a 'smooth'surface next to the lining and a rough outer surface.
